"...Once London was in the barons’ hands, King John had no option but to negotiate with them. The two sides met at Runnymede, on the River Thames near Windsor in the south of England, in June 1215. The demands of the barons were recorded in the document known as the Articles of the Barons. Following further discussions with the barons and clerics led by Archbishop Langton, King John granted the Charter of Liberties, subsequently known as Magna Carta, at Runnymede on 15 June 1215. On 19 June the rebel barons made their formal peace with King John and renewed their oaths of allegiance to him."
